DUMB STOVE FOR PARLORS.

Specification of Letters Patent No. 820, dated June 30, 1838.

To all whom it may concern:

Be it known that I, JOHN G. TREADW'ELL, of the city of Albany, in the county of Albany and State of New York, have invented an Improvement in Dumb Stoves for Parlors, which stove as improved by me I denominate the Compound Parlor Dumb Stove; and I do hereby declare that the following is a full and exact-description thereof. 0

Figure 1 in the accompanying drawing 1s a perspective view of the stove, in which there are three chambers, A, B, and C, connected together by pipes, or columns D', D, D, and E, E,E. Intothe lower chamber A,

. heated air is to be admitted through a pipe from a stove below; which pipe enters through the middle of vthe bottom plate of the dumb stove.

Within the pipes, or columns D, D, which connect the lower andmiddle chambers, there is a heat compartment F, F, formed like a box stove, its sides and endsiextending from one chamber to another. Gr 1s a door opening into this compartment. There is a movable plate in the bottom of this heat compartment, which when removed leaves it open to the lower chamber A.

Fig. 2 is a longitudinal vertical section of the stove through its middle; and Fig. 3, a similar cross section; in these figures the movable plate above alluded to is seen at a, a, by removing this the ashes or other matter collected may be cleared out. There is a damper inthe. bottom plate of this chamber as shown at b, b, Fig. 2, for governing the admission of air into the dumb stove,-

from that containing the fire. The columns, orjpipes D, D, D, all terminate at their upper ends in the spaces B, B,

Fig. 3, which spaces are bounded on the.

end columns, E, E, open below into the heat compartment F, and are furnished with dampers, for a reason WlllCll will presently appear. All the other pipes, or columns, are without dampers. There are two slid ng valves, or dampers whichallow a communication between the heat chamber and B, B; these are seen at 0,0, Fig. 3, and at 0, c, Fig. 2, which latter are the openings which are governed by sliding'shutters, ordampers, shown by the dotted lines. A direct communication may be made between the lower chamber A, and the heat compartment F, by means of a passage and damper made for that purpose. A partition (2, d, Fig. 2, at the rear end of the heat compartment, forms a space H, which opens below into chamber A, and above into compartment F. A shutter or damper 6, opens or closes the upper end of this space as may be desired. The

plate into which'the ends of the columns are inserted may be of cast iron; or cast iron rings may be fixed to sheet iron, to receive them.

Having thus fully described the manner in which I construct mydumb stove, I will now proceed to show how the same is to be used. When the heated air is admitted from the stovebelow, in which the fire is kept,

all the valves, or dampers which open into the heat chamber F, may be closed, and the heated air will then pass up through the 4 side pipes D, D, from the chamber A, to

the side spaces B, B, constituting'the a fire is made in the heat compartment the damper e, of the space H, is to be opened, when the smoke and heated air from the said fire will descend into the chamber A, and ascend through the respective side pipes, in the same way with the; heated air from the stove below, the dampers in E, E, being at the same time closed. If it'is de-' sired to heat the upperpart of the stove $01113 the damper 6, may be closed, and c, 0, opened, those in E, E, being still closed. By opening these latter the heated air and smoke from the fire in F, will pass directlythrough them into 0,. thus affording the means of regulating the heat in the most perfect manner.

What I claim as my invention, and desire and from said compartment, for the purto secure by Letters Patent, is pose, and substantially in the manner above The manner in which I have combined, set forth. and connected, the heat compartment with V 5 the other parts of the dumb stove; that is \Vitnesses:

to say by the combined operation of the respective openings and dampers leading into JOHN G. TREADVVELL.
